Abstract: A method and system for efficiently restoring synthetic full backup based virtual machines that include user checkpoints. Specifically, the method and system disclosed herein overcome a behavioral limitation exhibited in present virtual machine backup methodologies, where said methodologies ignore the presence of user checkpoints storing state for a virtual machine. In accounting for the user checkpoints while recovering a virtual machine, embodiments of the invention maintain restoration points for virtual machine state instantiated by the user, in addition to those instantiated by the system.

Abstract: A backup agent for generating backups includes a persistent storage and a backup manager. The persistent storage stores backup/restoration policies. The backup manager obtains production host computing resource characteristics associated with production hosts; performs a computing resource analysis of the production host computing resource characteristics to obtain resource profiles for each of the production hosts; performs an availability analysis of the obtained resource profiles to determine an application-level computing resources distribution for generating the backups; coordinates generating the backups using the application-level computing resource distribution and the backup/restoration policies to obtain the backups; and stores the obtained backups in backup storage.

Abstract: A method for managing backups includes mounting a block-based backup on a backup storage system to obtain a mounted backup, compressing the mounted backup to generate a compressed backup, and replicating the compressed backup to generate a plurality of compressed backups.

Abstract: A method for backing up databases includes generating a Database-Host Mapping (DHM) associated with a backup request in response to receiving the backup request, performing a database redistribution analysis based on the DHM and a preferred server order list (PSOL) to generate a Host-Database Mapping (HDM), and initiating a backup of a plurality of databases using the plurality of hosts specified in the HDM.

Abstract: A unified backup workflow process for different hypervisor configurations of virtual machines on different storage of a cluster leverages RCT-based backup functionality so that backup operations can be performed by a single host of the cluster. The process enables backing up together virtual machines that are local, as well as part of CSV or SMB storage using virtual machine level snapshots as checkpoints rather than volume level snapshots that were traditionally used. Backup data is sent to a backup server as a data stream rather than a file, which avoids the necessity of maintaining chains or structures that identify parent-child disks on the server.

Abstract: A Building Management System (BMS) includes a plurality of building subsystems and communications interface. The building subsystems include device(s) for controlling aspect(s) of the building subsystem. The communications interface receives commands from a cloud-based controller and a local client device. The commands from the cloud-based controller and local client device are structured to modify setting(s) for a device of the building subsystems. A BMS controller receives, via the communications interface from the cloud-based controller, a command for modifying a setting of a device for a first building subsystem. The BMS controller identifies a local setting of the device provided by the local client device. The BMS controller identifies a priority of the command from the cloud-based controller in relation to a priority of the local setting. The BMS controller controls the device based on the respective priorities.

Abstract: A remote backup agent that provides restoration services to virtual machines in accordance with one or more embodiments of the invention includes a persistent storage and a processor. The persistent storage stores a resource map. The processor obtains a restoration request for a virtual machine of the virtual machines; identifies a high computing resource availability host that does not host the virtual machine in response to obtaining the restoration request using the resource map; while the virtual machine is exposed, performs a restoration of the virtual machine in the identified high computing resource availability host; migrates the restored virtual machine to a second host that hosts the virtual machine; conceals the virtual machine; and exposes the restored virtual machine.

Abstract: In one example, a method includes obtaining cluster and machine configuration information, sending a restore request for one or more machines, and loading a backup of a virtual machine, the backup having been created by a federated backup process involving the physical proxy node, and the virtual machine includes data that resides on a virtual federated database that is an element of a cluster environment and to which respective databases of each of a plurality of nodes of the cluster environment are mapped. Next, the virtual machine is taken offline after the backup of the virtual machine has been loaded, and after the virtual machine has been taken offline, the virtual machine is removed from the node where it resides. The backup of the virtual machine is then restored, and the restored virtual machine brought online, after which the restored virtual machine is enabled as a cluster-wide virtual machine.

Abstract: In one example, a method includes receiving, at a physical proxy node, a backup request from a client outside the cluster environment, the backup request identifies a VM that is to be backed up, and including data that resides on a virtual federated database that is an element of the cluster environment and to which respective databases of each node of the cluster environment are mapped, and the backup request is received at the physical proxy node due to the position of the physical proxy node in a PSOL. Next, initiating, with an agent at the physical proxy node, a save program on the physical proxy node, and initiating, with the save program, a secondary save process on the physical proxy node that is a federated backup process and includes reading the VM identification from the backup request, and backing up the VM identified in the backup request.

Abstract: A production host for hosting virtual machines includes a persistent storage and a production agent. The persistent storage stores a backup groupings queue and a backup process stack. The production agent obtains backup generation requests for the virtual machines; in response to obtaining the backup generation requests, generates the backup groupings queue based on the backup generation requests; identifies a maximum parallelism of the production host based on resources utilized by a portion of the virtual machines specified by the backup groupings queue; consolidates the backup groupings queue to generate the backup process stack; and generates backups for virtual machines specified by the backup process stack in parallel based on the maximum parallelism.

Abstract: Systems and methods for performing differential and full data protection operations. Parameters that define minimum, interval, and maximum values are provided to an agent. These values relate to changes in the data or in a database. The agent monitors the database and backups are triggered in accordance with these values. A differential backup is not performed until the minimum value is reached and differential backups are performed only after subsequent intervals are reached. A full backup is performed once the maximum value is reached.

Abstract: A virtual machine backup process where a plurality of types of snapshots of the virtual machine coexist includes: obtaining a list of files comprising virtual hard disks and differencing virtual hard disks associated with the virtual machine; sorting the list of files to identify relationships and to generate a current tree in which differencing virtual hard disks point to corresponding parent virtual hard disks; comparing the current tree with a previous tree associated with the virtual machine from the last backup of the virtual machine; identifying differencing virtual hard disks in the current tree that are not present in the previous tree as incremental backup data; and backing up the incremental data. The incremental data is merged with a previous synthetic full backup of the virtual machine to generate a new synthetic full backup of the virtual machine.
